@wuilmerj24 could it be a CORS error?

@y4my4my4m I have cors enabled. I have also added them and it does not work either

Hi! Is there anything that gets printed in the console of your browser?

@darrachequesne Hello. Not in firefox. Probe in chrome and if it shows an error websocket.js: 87 Mixed Content: The page at 'https://admin.socket.io/#/' was loaded over HTTPS, but attempted to connect to the insecure WebSocket endpoint 'ws: //miip/socket.io/?EIO=4&transport=websocket '. This request has been blocked; this endpoint must be available over WSS.

For future readers:

You won't be able to reach a server without SSL from the admin UI, which is served from an HTTPS url: https://admin.socket.io/

But since SSL certs are more or less free these days, I don't think there's much we can do. Please reopen if needed!
